serialize not working with objects

bough

I am having problems when trying to add an object to a session. This seemed to be wroking okay at one point, but since I have re0installed php to version 5.2

this is my code below, and the error i am getting is that the unserialize is expecting a string, which the $_SESSION['cartid'] should be

this is the error i get

PHP Fatal error: Call to a member function addToCart() on a non-object in C:\Program Files\Apache Group\Apache2\htdocs\pebbles\userCart.php on line 27

if(isset($_SESSION['cartid']))
{
	$cart = unserialize($_SESSION['cartid']);
} else {	
	$cart = new Cart();	
	$_SESSION['cartid'] = $cart;
}
	$jewelID = $_GET['jewelID'];
	$image = $_GET['image'];
	$price = $_GET['price'];
	$name = $_GET['name'];
	$qty = $_GET['qty'];

$cart->addToCart($jewelID,$image,$price,$name,$qty);
$cart->showCart();	
?>

Am i getting the code wrong or could this be a configuration issue?

Any help would be fully appreciated

Are you sure that the object is serialized? It looks like you should have written:

$_SESSION['cartid'] = serialize($cart);

You don't need to use serialize() to have objects serialised in the session. It happens automatically and is completely transparent in normal operation.

Consider enabling error_reporting(E_ALL) across your entire application and having a very fussy error handler to spot this sort of problem earlier.

That's true, my mistake. Looks like I am having a rather bad day at PHP and SQL, with a whole thread full of errors and now this 🙁

Thanks for the reply everyone,

I think the problem must lie with my configuration, and most likely my php.ini settings, and likely need to adjust the error reporting_all settings which may be different from my previous version of php.ini

Thanks

Also, remember that when using an object stored in the session data, you must load the class definition for that object before you do the session_start();
